Rear View Mirrors - Exterior, Heated
Based on the Mirror Heat Request message received from the FCIM through the Medium Speed Controller Area Network (MS-CAN), the DDM controls the operation of the LH heated exterior mirror glass and the PDM controls the operation of the RH heated exterior mirror glass. On vehicles equipped with a LH exterior auto-dimming mirror, the LH exterior mirror glass takes longer to defrost than the RH exterior mirror glass due to differences in the mirror glass thickness.
